BIOL 204 - Introduction to Ecology

An introduction to the major divisions of ecology, including evolutionary and behavioural ecology, population and community ecology, and conservation biology/global change.  The course emphasizes an understanding of inter- and intra- specific interactions as well as spatial and temporal environmental patterns.   Theory will be applied to field situations and professional literature reviews.
